GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 415,124, dated November12, 1889.

Application filed Novemherll, 1887. Serial No. 254,921. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM M. PIATT, a citizen of the United States,residing at Mac-ocheek, in the county of Logan and State of Ohio, haveinvented a new and useful Improvement in Grain-Binders, of which thefollowing is a specification.

My invention is an improvement on those grain-binders which form the subject-matter of Letters Patent No. 377,731, dated February 7, 1888, andLetters Patent No. 384,07 2, dated June 5, 1888.

In my present improvement Itranspose the needle and knotting mechanismso as to bring the knotting mechanism above the binding-table and theneedle underneath the latter. The knotting mechanism I employ is of thatform which I have shown, described, and claimed in my said LettersPatent No. 384,072, and the operating mechanism which I employ is ofthat form which I have shown, described,

and claimed in my said Letters Patent No.2

My improvements consist in certain features of construction hereinafterdescribed, and pointed out in the claims.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which FigureI is aside elevation of myimprovecl grain-binder, partly in section,looking from the grain side. Fig. II is a vertical section of themachine on the line II II, Fig. I, looking from the rear side thereof.Fig. II is a plan view of the floor-plate of the casing of the knottingmechanism. Fig. 11 is a plan view of the knotting mechanism. Fig. III isan elevation of the machine, looking from the rear side. Fig. IV is anelevation of the machine, partly in section, looking from the stubbleside. Fig. V is a vertical transverse section of the machine through therunninggear. Fig. V1 is an elevation of' the grainwheel portion of themachine, looking from the grain side. Fig. VII is a side elevation ofthe drive-wheel portion of the machine, looking from the stubble side.

1 is my improved main frame,whichI show, describe, and claim in myLetters Patent, No. 377,731. This main frame has a binding-table leveltherewith, on which the grain is packed and bound without beingelevated. The main frame is supported on a drive-wheel 2 and grain-wheel3 bythe following means:

4 is the drive-wheel portion of the main frame, to which at its forwardpart is pivoted, by means of shaft 5 and stud 5 a yoke 5, embracing thedrive-wheel. In the upper part of the yoke is journaled an axle 8, onwhich the drive-wheel is mounted loosely. On the drive-wheel portion ofthe main frame, one at each side of the wheel, are rigidly securedupwardly-extending rack-bars 9, curved forward, so as to have theirracks concentric with the pivots of the yoke. Keyed to the ends of theaxle, on the outside of the yoke, are gear-wheels 10, meshing with therackbars. Secured to the stubble side of the yoke is a rack-segment 11,engaged by a springlatch 12 on a lever 13, keyed to the axle.

1 1 is a sheave or pulley keyed to the axle on the inner side of thedrive-wheel, between the latter and the yoke.

Mounted on the grain-Wheel 3, by a spindle '15, is a standard 16, onwhich the carrier or platform portion 17 of the main frameis adapted toslide.

Brackets 18 are secured to the main frame for supporting sheaves 19,under which is passed a chain or wire cable 20, secured at one end tothe sheave on the axle and at the other end to the top of the standard.

By the above-described devices the main frame can be lifted bodily andevenly without tilting, using the axle as a Windlass.

21 is the binder-supportingstock, having rearwardly-extending arm 22formed with a .head 23, on which is supported a casing 24,

having floor-plate 25 formedwith a needleslot.

26 is the main shaft, carrying at its front end the mutilated gear-wheel27, (operated by the means shown in my Letters Patent, No. 377,731,) andat its rear end the mutilated gear-wheel 28, formed with a cam-groove 29in its front face, as shown in dotted lines in Fig. II, and with acam-groove 30 in its periphery. The main shaft is formed with anextension 31, beyond the gear-Wheel 28, to provide support for a pendentframe 32, in which the knotter 33 has bearing in horizon tal positionwith its head toward the inner side of the head of the stock. Thisknotter is similar in construction. to that shown in Patent No. 384,072.The knottcr is formed with an outer jaw 34, inner hinged jaw 35, hollowshaft 39, and shank 37, sliding in the hollow shaft for opening andclosing the inner jaw. Surrounding the head of the knotter is a guard orshield 38, beyond which the knotter ope ates and by which the inner jawis concealed when the latter is. open. Contiguous to the guard or shieldare the gripper-plates or clamp-plates 39, between which the gripper 40rotates. The gripper is formed with a sleeve 41 and large gear-wheel 42.(See Fig. Ill) Directly beneath the outer end of the main shaft andparallel therewith is a counter-shaft 43, supported in hangers 44,secured to the arm of the stock and to the pendent frame, respectively.The countershaft carries the gear-wheel 45, having a delay-shoe 46, thecam 47, and the bevel gearwheels 48 and 49. The mutilated gear-wheel 28operates to rotate the gear-wheel 45, which is arrested in its movementby the shoe 46. The gear-wheel 48 meshes with a bevel gearwheel 50 onthe knotter-shaft to rotate the latter, and the gear-wheel 49 mesheswith the gear-wheel of the gripper for imparting rot-ation thereto inthe opposite direction.

51 is a lever secured by means of a bracket 52 to. the arm of the stockalongside the counter-shaft. The lever is connected to the shank 37 atone end and acted upon by the cam 47, to open the inner jaw of theknotter by sliding the shank in one direction, and pressed by a spring53, (see Fig. 11",) to close the inner jaw by sliding the shankin the opposite direction.

54 is a pivoted knife operating between the guard or shield and theclamp-plates. It is mounted on a stud 55, secured to the pendent frame32, and vibrated by an arm 59, working in the cam-groove 30.

57 is a rock-shaft beneath the table, having a crank-arm 57 at the frontof the stock connected by a pitman 58 with a wrist-pin 59 on themutilated gear-wheel 27. This rockshaft carries at its rear end a curvedneedle 60, working upwardly through a slot in the table and through theslot in the bottom plate of the casing across the path of the knotterand gripper.

61 is a cut-off link secured to the outer end of the needle, workin gupwardly through the needle-slot in the table, and having rollers 62beneath the table running in ways 63, also beneath the table. The needleand link cause a complete separation of the incoming grain from thebundle. To the lower portion of the stock and in a frame 71 on the headis journaled an outer ejector-shaft 67, having gear-wheel G9, engaged bythe mutilated gearwheel 27.

83 is the main apron, which delivers the grain to the packers.

Journaled in the packer-frame are the outer and inner packer-shafts 7 2and 7 3, supporting camtraeks 74. The bottonpparts of the cam-tracks aresuspended onlinks'75, to adapt them to be raised and lowered by a lever79, having a pin 77, working in the camgroove 29 of the wheel 28, and atthe outer end supporting a pivot-pin 78, connected to the bottom partsby pitmen 79.

are sprocket-wheels, 81 chains, and 82 fingers of the packers, whichtransfer the grain delivered to them by the main apron to a position inadvance of the path 01": the needle. The packer is located between thebinding devices and the inner end of the main apron.

84 is a short inner ejector-shaft supported beneath the arm of thestock. Supported on the outer and inner ejector-shafts, beneath the armof the stock, are cam-tracks 85 and sprocket-wheels 86, carrying thesprocketchains 87 and fingers 88. Mounted in brackets 89 on the stubbleside of the stock is the compressor-shaft 90, having at its front end ageanwheel 64, engaged-by the mutilated gear-wheel 27, and at its rearend a crank 91. Keyed to the outer ejector-shaft are cams 98, havinggrooves 99 on their faces.

100 are links pivoted to the head and carrying at their lower ends a rod101, whose ends work in the grooves. Supported on the rod is a combinedcompressor and retainingfinger 94. The inner end of this finger isconnected with the crank 91 on the compressorshaft by means shown inLetters Patent N 0. 377,731, consisting of a cylinder 102, pistonrod 92,and a spring 103 between the pistonhead and cylinder-head.

Secured to a crank 96 on the outer ejectorshaft is a dischargingfinger95, the upper end of the finger being connected by a link 97 wit-l1 thehead of the stock, so as to be restricted to an elliptical path.
